Description
This application is a divisional of U.S. patent application Ser. No. 12/231,376 filed on Sep. 2, 2008 now U.S. Pat. No. 7,856,166 and entitled “High-Density Patch-Panel Assemblies for Optical Fiber Telecommunications,” the entire contents of which are hereby incorporated by reference.
The present invention relates generally to optical fiber telecommunications equipment and networks, and in particular relates to patch panel assemblies that can contain a relatively high density of patch panel modules.
Typical optical telecommunication systems and networks include one or more telecommunications data centers that provide large numbers of optical and electrical cable connections that join various types of network equipment. The typical system also includes a number of outlying stations that extend the system into a network. Examples of network equipment include electrically-powered (active) units such as optical line terminals (OLTs), optical network terminals (ONTs), network interface devices (NIDs), servers, splitters, combiners, multiplexers, switches and routers, fanout boxes and patch panels. This network equipment is often installed within cabinets in standard-sized equipment racks. Each piece of equipment typically provides one or more adapters where optical or electrical patch cables (“jump cables”) can be physically connected to the equipment. These patch cables are generally routed to other network equipment located in the same cabinet or in another cabinet.
A common problem in telecommunications systems, and in particular with optical telecommunications equipment, is space management. Current practice in telecommunications is to utilize standard electronics racks or frames that support standards-sized stationary rack-mounted housings with widths of 19 or 23 inches horizontal spacing. Vertical spacing has been divided into rack units “U”, where 1U=1.75 inches as specified in EIA (Electronic Industries Alliance) 310-D, IEC (International Electrotechnical Commission) 60297 and DIN (“German Institute for Standardization”) 41494 SC48D. The housings may be fixed, slide-out, or swing-out patch/splice panels or shelves. However, the configurations and sizes of present-day housings for optical telecommunications equipment have been defined largely by the properties of the fiber optic cables that connect to the devices supported by the housings. In particular, the configurations and sizes have been established based on the particular ability of the fiber optic cables and optical fibers therein to interface with the devices without exceeding the bending tolerance of the fiber optic cable and/or the optical fibers. This has resulted in telecommunications equipment that occupies relatively large amounts of space, and in particular a relatively large amount of floor space in a central office of a telecommunications network. It has also lead to data center patch panels being increasingly overpopulated due to connector and cable volumes.
The present invention relates to patch panel assemblies that can support a relatively high density of patch panels. The patch panel assemblies have a configurations that takes advantage of cable fibers and jumper fibers that are bend-insensitive. The use of multiple rows of patch panel modules serves to distribute the density to enable ease of finger access to the modules, and facilitates the use of RFID systems that have difficultly reading densely packed RFID tags.
Accordingly, a first aspect of the invention is a patch panel assembly for a telecommunication data center for providing optical connections using bend-insensitive optical fiber cables. The assembly includes a rectangular, box-like housing having an interior region, a front side and a back side. The housing is sized to be operably supported by a standard telecommunications rack. The assembly further includes a front mounting frame and at least one interior mounting frame, wherein the mounting frames are configured to support at least one reduced-form-factor patch panel module.
A second aspect of the invention is a patch panel module. The patch panel module includes a substantially rectangular module housing that includes a front side having at least one angled facet, an opposing back side, opposing ends, and opposing sidewalls that define an interior region. The module includes at least one jack arranged on the at least one angled facet, with the at least one jack defining one or more front-side ports. The module includes at least one backside port operably connected to the at least one jack via at least one bend-insensitive cable fiber contained within the housing interior region. A lengthwise open channel is formed in the backside of the module housing and is sized to accommodate an external bend-insensitive optical cable.
A third aspect of the invention is a patch panel assembly for a telecommunication data center for providing optical connections using bend-insensitive optical fiber cables. The assembly includes a rectangular, box-like housing having opposing side walls and a back panel that defines an interior, the housing sized to be operably supported by a standard telecommunications rack. The assembly includes a drawer having a front end and a floor panel and is configured to slide in and out of the housing interior, and is also configured to support an array of patch panel modules on the floor panel in a substantially horizontal configuration. The assembly also includes at least one movable cable guide arranged in the housing and configured to guide at least one bend-resistant fiber optic cable and to move to accommodate the sliding of the drawer in and out of the housing.
It is to be understood that both the foregoing general description and the following detailed description present embodiments of the invention, and are intended to provide an overview or framework for understanding the nature and character of the invention as it is claimed. The accompanying drawings are included to provide a further understanding of the invention, and are incorporated into and constitute a part of this specification. The drawings illustrate the various exemplary embodiments of the invention, and together with the description serve to explain the principals and operations of the invention.
Reference is now made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same or similar reference numerals are used throughout the drawings to refer to the same or similar parts. It should be understood that the embodiments disclosed herein are merely examples, each incorporating certain benefits of the present invention. Various modifications and alterations may be made to the following examples within the scope of the present invention, and aspects of the different examples may be mixed in different ways to achieve yet further examples. Accordingly, the true scope of the invention is to be understood from the entirety of the present disclosure, in view of but not limited to the embodiments described herein.
Terms such as “horizontal,” “vertical,” “front,” “back,” etc., are used herein for the sake of reference in the drawings and ease of description and are not intended to be strictly limiting either in the description or in the claims as to an absolute orientation and/or direction. Also, the term “bend-insensitive fiber optic cable” is intended to include cable that includes one or more bend-insensitive optical fibers.
Bend-Insensitive Optical Fibers
Example embodiments of the present invention make use of bend-insensitive or “bend performance” fibers such as those in the form of so-called “nanostructure” or “holey” optical fibers. There are a number of such fibers on the market today. Nanostructure fibers have one or more regions with periodically or aperiodically arranged small holes or voids, which make the fiber extremely bend insensitive. Examples of such optical fibers are described in, for example, U.S. Pat. No. 6,243,522, pending U.S. patent application Ser. No. 11/583,098 filed Oct. 18, 2006 (hereinafter, “the Corning nanostructure fiber patents and patent applications”), all of which are assigned to Corning Incorporated, and all of which are incorporated by reference herein.
Bend-insensitive fibers as used in the present invention include, for example, nanostructure fibers of the type available from Corning, Inc., of Corning, N.Y., including, but not limited to, single-mode, multi-mode, bend performance fiber, bend-optimized fiber and bend-insensitive optical fiber. Nanostructure fibers are advantageous in that they allow for the patch panel modules and patch panel assemblies of the present invention to have fibers with relatively small-radius bends while optical attenuation in the fibers remains extremely low. One example of a bend-insensitive optical fiber includes a core region and a cladding region surrounding the core region, the cladding region comprising an annular hole-containing region comprised of non-periodically disposed holes such that the optical fiber is capable of single mode transmission at one or more wavelengths in one or more operating wavelength ranges. The core region and cladding region provide improved bend resistance, and single mode operation at wavelengths preferably greater than or equal to 1500 nm, in some embodiments also greater than about 1310 nm, in other embodiments also greater than 1260 nm. The optical fibers provide a mode field at a wavelength of 1310 nm preferably greater than 8.0 μm, and more preferably between about 8.0 and 10.0 μm.
One type of nanostructure optical fiber developed by Corning, Inc., has an annular ring of non-periodic airlines (of diameter ˜1×10−7 m) that extend longitudinally along the length of the fiber. The region with the ring of airlines has a reduced apparent or average index of refraction, because air has an index of refraction of approximately 1 compared to the fused silica matrix refractive index of approximately 1.46. The ring of airlines is positioned to create a refractive index profile that enables superior bend performance (optically) and significantly smaller minimum bend radius specifications.
In an example embodiment, nanostructure optical fiber 12 includes a core region (“core”) 20, a nanostructure region 30 surrounding the core, and an outer cladding region 40 (“cladding”) surrounding the nanostructure region. Other ring-type configurations for nanostructure optical fiber 12 are also known. A protective cover or sheath (not shown) optionally covers outer cladding 40.
In an example embodiment, nanostructure region 30 comprises a glass matrix (“glass”) 31 having formed therein non-periodically disposed holes (also called “voids” or “airlines”) 32, such as the example voids shown in detail in the magnified inset of FIG. 2A . In another example embodiment, voids 32 may be periodically disposed, such as in a photonic crystal optical fiber, wherein the voids typically have diameters between about 1×10−6 m and 1×10−5 m. Voids 32 may also be “non-periodic airlines. In an example embodiment, glass 31 is fluorine-doped while in another example embodiment the glass is undoped pure silica. By “non-periodically disposed” or “non-periodic distribution,” it is meant that when one takes a cross-section of the optical fiber (such as shown in FIG. 2A ), the voids 32 are randomly or non-periodically distributed across a portion of the fiber.
Cross sections similar to FIG. 2A taken at different points along the length of nanostructure optical fiber 12 will reveal different cross-sectional hole patterns, i.e., various cross-sections will have different hole patterns, wherein the distributions of holes and sizes of holes do not match. That is, the holes are non-periodic, i.e., they are not periodically disposed within the fiber structure. These holes are stretched (elongated) along the length (i.e. in a direction generally parallel to the longitudinal axis) of the optical fiber (and thus have a longer dimension along the length of the fiber), but do not extend the entire length of the entire fiber for typical lengths of transmission fiber. While not wishing to be bound by theory, it is believed that the holes extend less than a few meters, and in many cases less than 1 meter along the length of the fiber.
If non-periodically disposed holes/voids 32 are employed in nanostructure region 30, it is desirable in one example embodiment that they be formed such that greater than 95% of and preferably all of the holes exhibit a mean hole size in the cladding for the optical fiber which is less than 1550 nm, more preferably less than 775 nm, most preferably less than about 390 nm. Likewise, it is preferable that the maximum diameter of the holes in the fiber be less than 7000 nm, more preferably less than 2000 nm, and even more preferably less than 1550 nm, and most preferably less than 775 nm. In some embodiments, the fibers disclosed herein have fewer than 5000 holes, in some embodiments also fewer than 1000 holes, and in other embodiments the total number of holes is fewer than 500 holes in a given optical fiber perpendicular cross-section. Of course, the most preferred fibers will exhibit combinations of these characteristics. Thus, for example, one particularly preferred embodiment of optical fiber would exhibit fewer than 200 holes in the optical fiber, the holes having a maximum diameter less than 1550 nm and a mean diameter less than 775 nm, although useful and bend resistant optical fibers can be achieved using larger and greater numbers of holes. The hole number, mean diameter, max diameter, and total void area percent of holes can all be calculated with the help of a scanning electron microscope at a magnification of about 800× to about 4000× and image analysis software, such as ImagePro, which is available from Media Cybernetics, Inc. of Silver Spring, Md., USA.
In an example embodiment, holes/voids 32 can contain one or more gases, such as argon, nitrogen, or oxygen, or the holes can contain a vacuum with substantially no gas; regardless of the presence or absence of any gas, the refractive index of the hole-containing region is lowered due to the presence of the holes. The holes can be periodically or non-periodically disposed. In some embodiments, the plurality of holes comprises a plurality of non-periodically disposed holes and a plurality of periodically disposed holes. Alternatively, or in addition, as mentioned above, the depressed index can also be provided by downdoping the glass in the hole-containing region (such as with fluorine) or updoping one or both of the surrounding regions.
Nanostructure region 30 can be made by methods that utilize preform consolidation conditions, which are effective at trapping a significant amount of gases in the consolidated glass blank, thereby causing the formation of voids in the consolidated glass optical fiber preform. Rather than taking steps to remove these voids, the resultant preform is used to form an optical fiber with voids, or holes, therein. As used herein, the diameter of a hole is the longest line segment whose end points are disposed on the silica internal surface defining the hole when the optical fiber is viewed in a perpendicular cross-section transverse to the optical fiber central axis AF.
SEM analysis of the end face of an example nanostructure optical fiber 12 showed an approximately 4.5 micron radius GeO2—SiO2 void-free core (having an index of approximately +0.34 percent delta versus silica) surrounded by a 11-micron outer radius void-free near cladding region surrounded by 14.3-micron outer radius non-periodic void-containing cladding region (ring thickness of approximately 3.3 μm), which is surrounded by a void-free pure silica outer cladding having an outer diameter of about 125 μm (all radial dimensions measured from the center of the optical fiber).
The nanostructure region comprised approximately 2.5 percent regional area percent holes (100% N2 by volume) in that area with an average diameter of 0.28 μm and the smallest diameter holes at 0.17 μm and a maximum diameter of 0.48 μm, resulting in a total of about 130 holes in the fiber cross-section. The total fiber void area percent (area of the holes divided by total area of the optical fiber cross-section×100) was about 0.05 percent. Optical properties for this fiber were 0.36 and 0.20 dB/Km at 1310 and 1550 nm, respectively, and a 22-meter fiber cable cut-off of about 1250 nm, thereby making the fiber single mode at wavelengths above 1250 nm.
The nanostructure optical fibers as used herein may or may not include germania or fluorine to adjust the refractive index of the core and/or cladding of the optical fiber, but these dopants can also be avoided in the intermediate annular region and instead, the holes (in combination with any gas or gases that may be disposed within the holes) can be used to adjust the manner in which light is guided down the fiber core. The nanostructure region may consist of undoped (pure) silica, thereby completely avoiding the use of any dopants in the hole-containing region, to achieve a decreased refractive index, or the nanostructure region may comprise doped silica, e.g. fluorine-doped silica having a plurality of holes. In one set of embodiments, the core includes doped silica to provide a positive refractive index relative to pure silica, e.g. germania doped silica. The core region is preferably hole-free.
Such fiber can be made to exhibit a fiber cut-off of less than 1400 nm, more preferably less than 1310 nm, a 20-mm macrobend induced loss at 1550 nm of less than 1 dB/turn, preferably less than 0.5 dB/turn, even more preferably less than 0.1 dB/turn, still more preferably less than 0.05 dB/turn, yet more preferably less than 0.03 dB/turn, and even still more preferably less than 0.02 dB/turn, a 12-mm macrobend induced loss at 1550 nm of less than 5 dB/turn, preferably less than 1 dB/turn, more preferably less than 0.5 dB/turn, even more preferably less than 0.2 dB/turn, still more preferably less than 0.1 dB/turn, still even more preferably less than 0.05 dB/turn, and an 8-mm macrobend induced loss at 1550 nm of less than 5 dB/turn, preferably less than 1 dB/turn, more preferably less than 0.5 dB/turn, and even more preferably less than 0.2 dB/turn, and still even more preferably less than 0.1 dB/turn.
The nanostructure fibers used herein may be multimode. Multimode optical fibers disclosed herein comprise a graded-index core region and a cladding region surrounding and directly adjacent to the core region, the cladding region comprising a depressed-index annular portion comprising a depressed relative refractive index relative to another portion of the cladding. The depressed-index annular portion of the cladding is preferably spaced apart from the core. Preferably, the refractive index profile of the core has a parabolic shape. The depressed-index annular portion may, for example, comprise glass comprising a plurality of voids, or fluorine-doped glass, or fluorine-doped glass comprising a plurality of voids.
In some embodiments, the multimode optical fiber comprises a graded-index glass core; and a cladding surrounding and in contact with the core, the cladding comprising a depressed-index annular portion surrounding the core, said depressed-index annular portion having a refractive index delta less than about −0.2% and a width of at least 1 micron, said depressed-index annular portion spaced from said core at least 0.5 microns.
The multimode optical fiber disclosed herein exhibits very low bend induced attenuation, in particular very low macrobending induced attenuation. In some embodiments, high bandwidth is provided by low maximum relative refractive index in the core, and low bend losses are also provided. Consequently, the multimode optical fiber may comprise a graded-index glass core; and an inner cladding surrounding and in contact with the core, and a second cladding comprising a depressed-index annular portion surrounding the inner cladding, said depressed-index annular portion having a refractive index delta less than about −0.2% and a width of at least 1 micron, wherein the width of said inner cladding is at least 0.5 microns and the fiber further exhibits a 1 turn 10 mm diameter mandrel wrap attenuation increase, of less than or equal to 0.4 dB/turn at 850 nm, a numerical aperture of greater than 0.18, and an overfilled bandwidth greater than 1.5 GHz-km at 850 nm.
Using the designs disclosed herein, 50 micron diameter core multimode fibers can been made which provide (a) an overfilled (OFL) bandwidth of greater than 1.5 GHz-km, more preferably greater than 2.0 GHz-km, even more preferably greater than 3.0 GHz-km, and most preferably greater than 4.0 GHz-km at a wavelength of 850 nm. These high bandwidths can be achieved while still maintaining a 1 turn 10 mm diameter mandrel wrap attenuation increase at a wavelength of 850 nm, of less than 0.5 dB, more preferably less than 0.3 dB, even more preferably less than 0.2 dB, and most preferably less than 0.15 dB. These high bandwidths can also be achieved while also maintaining a 1 turn 20 mm diameter mandrel wrap attenuation increase at a wavelength of 850 nm, of less than 0.2 dB, more preferably less than 0.1 dB, and most preferably less than 0.05 dB, and a 1 turn 15 mm diameter mandrel wrap attenuation increase at a wavelength of 850 nm, of less than 0.2 dB, preferably less than 0.1 dB, and more preferably less than 0.05 dB. Such fibers are further capable of providing a numerical aperture (NA) greater than 0.17, more preferably greater than 0.18, and most preferably greater than 0.185. Such fibers are further simultaneously capable of exhibiting an OFL bandwidth at 1300 nm which is greater than 500 MHz-km, more preferably greater than 600 MHz-km, even more preferably greater than 700 MHz-km. Such fibers are further simultaneously capable of exhibiting minimum calculated effective modal bandwidth (Min EMBc) bandwidth of greater than about 1.5 MHz-km, more preferably greater than about 1.8 MHz-km and most preferably greater than about 2.0 MHz-km at 850 nm.
Preferably, the multimode optical fiber disclosed herein exhibits a spectral attenuation of less than 3 dB/km at 850 nm, preferably less than 2.5 dB/km at 850 nm, even more preferably less than 2.4 dB/km at 850 nm and still more preferably less than 2.3 dB/km at 850 nm. Preferably, the multimode optical fiber disclosed herein exhibits a spectral attenuation of less than 1.0 dB/km at 1300 nm, preferably less than 0.8 dB/km at 1300 nm, even more preferably less than 0.6 dB/km at 1300 nm. In some embodiments it may be desirable to spin the multimode fiber, as doing so may in some circumstances further improve the bandwidth for optical fiber having a depressed cladding region. By spinning, we mean applying or imparting a spin to the fiber wherein the spin is imparted while the fiber is being drawn from an optical fiber preform, i.e. while the fiber is still at least somewhat heated and is capable of undergoing non-elastic rotational displacement and is capable of substantially retaining the rotational displacement after the fiber has fully cooled.
In some embodiments, the numerical aperture (NA) of the optical fiber is preferably less than 0.23 and greater than 0.17, more preferably greater than 0.18, and most preferably less than 0.215 and greater than 0.185.
In some embodiments, the core extends radially outwardly from the centerline to a radius R1, wherein 20≦R1≦40 microns. In some embodiments, 22≦R1≦34 microns. In some preferred embodiments, the outer radius of the core is between about 22 to 28 microns. In some other preferred embodiments, the outer radius of the core is between about 28 to 34 microns.
In some embodiments, the core has a maximum relative refractive index, less than or equal to 1.2% and greater than 0.5%, more preferably greater than 0.8%. In other embodiments, the core has a maximum relative refractive index, less than or equal to 1.1% and greater than 0.9%.
In some embodiments, the optical fiber exhibits a 1 turn 10 mm diameter mandrel attenuation increase of no more than 1.0 dB, preferably no more than 0.6 dB, more preferably no more than 0.4 dB, even more preferably no more than 0.2 dB, and still more preferably no more than 0.1 dB, at all wavelengths between 800 and 1400 nm.
Fiber Bend Angle and Bend Diameter
In an example embodiment, the bend-insensitive optical fibers used in the present invention have bends like bend B with a bend diameter DB as small as 10 mm. This, in part, allows for the patch panel modules of the present invention to be made relatively compact and to allow for the patch panel assemblies to contain a relatively high density of patch-panel modules and thus a high-density of jacks and ports for establishing optical connections.
In the discussion hereinafter, for the sake of convenience, reference number 12 is used to refer to bend-insensitive fibers generally, with bend-insensitive “cable fibers” carried by a bend-insensitive fiber optic cable being identified as 12C to distinguish from bend-insensitive “jumper fibers,” which are identified as 12J.
Reduced Form Factor Patch Panel Module
Each jack 90 defines either one or two ports 92 open at a front side 96 and configured to receive a connectorized end 13J of a jumper fiber 12J. Each jack 90 also includes backside ports 98 where one or more cable fibers 12C from bend-insensitive fiber optic cable 70 are attached. In an example embodiment, module 50 includes two rows of six jacks 90, as shown. Further to the example embodiment, one or two cable fibers 12C are connected to each jack at back side ports 98 (i.e., one cable fiber for each port 92), as illustrated in FIG. 3B .
Because cable fibers 12C are bend insensitive, they can and do have tight bends that allow them to fit into the tight space of interior 58 so as to be connected to jacks 90 at backside ports 98. The use of bend-insensitive cable fibers 12C within interior 58 also allows for the module housing 56 to have reduced dimensions and thus a reduced form factor. In an example embodiment, housing 56 has dimensions of length L1=4.62 inches, width W1=1.295 inches and Depth D1 between about 2 inches and about 3 inches, e.g., 2.36 inches. Because depth D1 can be almost half that of the corresponding prior art patch panel module, the volume of interior 58 is reduced by close to 40% over the prior art. This in turn allows for a higher density of ports 92 to be supported in a standard-size patch panel assembly.
Bend-insensitive cable fibers 12C also facilitate the connection of one or two cables 70 to patch panel module 50 at an angle relative to backside wall 60. This angled connection facilitates a high-density arrangement of patch panel modules 50 in a patch-panel assembly, as discussed in greater detail below. In an example embodiment, the angle θ formed by cable 70 relative to the normal N to backside wall 60 is between about 60 degrees and 70 degrees, as shown in FIG. 3C . Note that in an example embodiment the use of one or two V-shaped indentations 61 serves to reduce the volume of interior 58 even further. This additional reduction in interior volume is also made possible by the use of bend-insensitive cable fibers 12C.
Mounting-Frame-Type Patch Panel Assembly
In an example embodiment, housing 152 has standard dimensions of length L2=17 inches (˜10 U), Height H2=6.88 inches (˜4U) and a depth D2=15.51 inches (˜9U) (see FIG. 7 ) so that patch panel assembly 150 fits into a standard-sized 19″ equipment rack as used in telecommunications systems (e.g., at data centers, etc.) as specified by EIA-310-D (Cabinets, Racks, Panels and Associated Equipment).
In an example embodiment, housing 152 includes a flat shelf 182 that connects sidewalls 160 at housing bottom 155 at front 156, and that extends beyond the sidewall front edges 166 at front 156. Shelf 182 has an upper surface 183, a front end 184 and a back end 185. In an example embodiment, front end 184 includes at least one hinge 196 that attaches a front cover 190 to frame 152 at front 156 so that the front cover folds downward. Front cover 190 has respective inner and outer surfaces 192 and 194. In an example embodiment, front cover 190 is transparent. Front cover optionally includes a clip 197 that is configured to engage an edge 199E of a clip plate 199 that is connected to interior mounting frame 210I and that extends over front mounting plate 210F.
Each mounting frame front face 212 presents a mounting surface configured so that at least one and preferably more (e.g., preferably ten to twelve) patch panel modules 50 can be mounted thereto, e.g., at threaded holes 218 configured to correspond to mounting holes 84 of patch panel modules 50. In an example embodiment illustrated in FIG. 5 , one or more of the mounting frames 210 are made up of two sections 220, each of which are connected to respective sidewalls 160 via respective hinges 224 that allows the sections swing outwardly. In FIG. 5 , front mounting frame 210F is shown as being made up of two sections. This geometry allows access to mounting panels 210 located immediately behind another mounting panel. In an alternative embodiment, one or more of mounting frames 210 are hinged on one side with one or more hinges 224 so that the entire hinged mounting frame swings open in door-like fashion.
In an example embodiment, back panel 157 is hinged in the same manners as front mounting panel 210I in order to provide access to patch panel modules 50 mounted in the adjacent internal mounting frame 210I.
In an example embodiment, mounting frames 210 are configured to support at least one patch panel module 50, and preferably is configured to support between 10 to 12 reduced-volume patch panel modules.
Hinge Assembly for Cable Routing
An aspect of the present invention is directed to routing cables 70 to and from mounting-frame-type patch panel assembly 150, as well as managing the distribution of cables (including cable fibers 12C) within the patch panel assembly.
In an example embodiment, the routing of cables 70 and/or cable fibers 12C within housing interior region 200 and between patch panels 50 is facilitated by having a special hinge assembly 224 for front mounting frame 210F. FIG. 8A is a perspective exploded view of an example embodiment of front mounting frame 210F and a housing portion 152P. Front mounting frame 210F has a number of mounting apertures 213F in front face 212F for mounting patch panel modules 50. Front mounting frame 210F has a curved inner hinge portion 224I at one of the front mounting frame ends 216. Curved inner hinge portion 224I includes top and bottom surfaces 223 with vertically aligned holes 223H formed therein.
Cable Distribution Box
In an example embodiment, open topside 306 includes inwardly extending flexible tabs 312 that serve to keep cable 70 from unwinding, while providing easy access to the portion of the cable wound and stored within interior region 314. In an example embodiment, cable distribution box 300 is made from polymer, plastic or sheet metal.
Patch Panel Assembly with Hinge Assembly and Cable Distribution Box
Some of cables 70 having portions thereof stored in cable distribution box 300 are connected to patch panel modules 50 of internal mounting frame 210I at respective patch panel module backsides 60. As indicated by arrows A70, other cables 70 are routed beneath internal mounting frame 210I along bottom 155 and through hinge assembly 224 and to the backsides 60 of patch panel modules 50 mounted in front mounting frame 210F. In an example embodiment, a floor panel FP is arranged adjacent bottom panel 155 and creates a “false floor” that defines a sub-region 323 to interior 200 sized to accommodate the routing of one or more cables 70.
Drawer-Type Patch Panel Assembly
With continuing reference to FIGS. 11A through 11D , drawer 270 is configured to clearance fit within interior 200 and to slide in and out thereof over bottom panel 242. In an example embodiment, drawer 270 has a floor panel 274 with a front end 276, a back end 278, and opposite side edges 280. Floor panel 274 supports an array of reduced-volume patch panel modules 50 arranged in one or more rows and in a horizontal configuration with jacks 90 pointing upward at an angle towards the front of drawer 270. Here, drawer 270 obviates the need for vertically oriented module frames 210 as described above. Example patch panel modules 50 suitable for use in this configuration are discussed in greater detail below. Note that the backside walls 60 of the patch panel modules 50 are face-down on floor panel 274.
In an example embodiment, each patch panel module 50 includes six jacks 90 each having one or two ports 92. Further in an example embodiment as shown in FIG. 11D , the array of patch panel modules 50 is made up of two rows of eighteen modules, for a total of 36 modules and thus 216 jacks 90 and thus 216 or 432 ports 92, depending on whether the jacks are single or dual port. Thus, in an example embodiment, the drawer-type patch panel assembly 150 provides between 216 ports/U and 216 ports/U. Jacks 90 arranged on patch panel modules 50 at an angle relative to vertical and angled toward the front of drawer 270.
In an example embodiment, housing assembly 150 further includes a cable distribution box 300 arranged near the back end 278 of floor panel 274 behind patch panel modules 50. As discussed above, cable distribution box 300 is configured to receive bend-insensitive fiber optic cables 70 and store a portion of them while distributing them to patch panel modules 50.
In an example embodiment best illustrated in FIG. 11B , housing bottom panel 242 includes at least one cable guide 350 configured to guide cables 70 that enter housing interior 200 from housing apertures 250. In an example embodiment, cable guide 350 includes at least one guide member 356. In an example embodiment, guide member 356 includes tray section 360 with sides 362. Guide member 356 may also include a number of spaced apart containment members 366 connected to respective sides so as to form an open tunnel-like channel 360 that contains one or more of cables 70. One end of guide member 356 is located at or near aperture 250, while the other end is located at back end 278 of drawer floor panel 274.
In an example embodiment, cable guide 350 includes two articulated and curved guide members 356 that fold in and reside at housing back panel 157 in a stacked fashion when drawer 270 is closed, and that fold out and reside near housing sidewalls 160 when the drawer is opened. This folding action serves to control the distribution and bending of {fiber optic cables} being held within guide members 356. In an example embodiment, one guide member 356 is arranged at a different (e.g., lower) height than the other so that the lower guide member passes underneath the higher guide member when the two are folded together, as shown in FIG. 11D .
Patch Panel Module for Drawer-Type Patch Panel Assembly
Patch panel module includes an open channel 420 formed in backside wall 60 and sized to accommodate cable 70 when patch-panel module 50 is placed with backside 60 against floor panel 274. FIG. 13C is a view of backside 60 of patch panel module 50 as would be seen by looking through floor panel 274 if the floor panel were transparent. Note that the cable 70 that attaches to patch panel module 50 of FIGS. 13A and 13B does so via end 407 of housing 56.
Rack Assembly
Aspects of the invention includes a rack assembly that houses either the drawer-type patch panel assemblies or mounting-frame-type patch panel assemblies described above. Because both of these types of patch panel assemblies 150 preferably have a standard 4U configuration, both can be housed in the same rack assembly.
In a preferred embodiment, rack assembly 500 comprises a standard 19″ equipment rack having an inside width of 17.75″, on-center rail hole pairs separated by 18.3″ on the front of the rack, and is divided up by standard 1.75″ increments, where each increment is called a “unit” or “U” for short and includes three complete hole pairs. Frame 506 defines an interior region 530 within which patch panel assemblies 150 reside. Drawers 270 of the drawer-type patch panel assemblies 150 preferably include handles 550.
The inside surface of side bars 510 and 512 are configure to allow for patch panel assemblies 150 to be arranged in a stacked manner between the side bars and thus within frame interior region 530, as shown. In one example embodiment, the inside surface of side bars 510 and 512 are smooth, while in another example embodiment they include guide tabs (not shown) that facilitate the stacking and support of housing assemblies 150 within frame 506. In an example embodiment, side bars 510 and 512 are configured so that front and back portions of the patch panel assemblies protrude from the front side 518 and backside 520 of frame 506, as illustrated in FIGS. 16 and 17 .
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit and scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
